Even though I enjoyed the series at first, it's no longer anything I follow. It is a hard life they choose, but a profitable one. Many of them work 5-6 months a year, and play the rest.
Discovery/History Channel (and such) used to actually have good programming. Real Science/History, etc. Once they hit with this show, and it hit big, all the rest of the "learning channels" followed suit. Now you can't find anything on any of them except "Swamp People/Ax Men/ Deadliest Catch or whatever End of the World/ UFO crap they can find". Not a single one of those shows contributes an iota of value. Even Science Channel has followed the rest with "Mantracker". Smithsonian might be the last bastion of actual learning on TV.
Sad, our viewing habits as a country.
